Dotted Bee-fly Bombus discolor

We are seeing Dotted Bee-flies around in Worcestershire this spring, with several records from the Wyre Forest area, and wonder if this is undergoing a range expansion. To distinguish this species from the more frequently recorded Dark-edged Bee-fly Bombylius major, wait until the fly has settled and look carefully for dots on the wings. The black hairs at the end of the abdomen are conspicuous even in flight. I have found this fly less easy to approach for photography than the obliging Dark-edged Bee-fly.

Tachinid Fly

This medium sized fly is scarce but can be locally common. Very much a temperate region fly it is only found in Northern Europe except for Norway. Seen sunbathing along the Dowles Brook on the 5th April

Little Black Puddings (Dasineura pteridis)

These galls are commonly found on Bracken in the summer and autumn. They are caused by the larvae of a Cecidomyiid gall midge which cause these black, shiny, and rolled swellings to occur on the fronds. The mature larvae leave the galls to pupate in the soil, and there are two generations a year.

Non-biting Midge Chironomid larvae

The adult flies in the family Chironomidae (the non-biting midges), look a little like mosquitoes, and their larvae are aquatic or semi-aquatic. Some of these are bright red and commonly called bloodworms due to the presence of haemoglobin in their circulatory fluid so that they can carry oxygen which enables then to live in polluted water in almost anaerobic conditions. Some build tubes underwater from a mixture of mud and saliva, and these can be seen in Wyre during the summer, especially where the puddles are drying out. A few of these tubes placed in an aquarium have provided views of the bloodworms inside the tubes, and repairing those that were damaged.

Oxyna parietina

This attractive Tephritid picture-wing fly is always associated with Mugwort Artemisia vulgaris. The larvae bore into the stems and feed within them. There are not many records from this area. A few adults were found on Mugwort along the banks of the River Severn north of Bewdley.

Rhingia campestris

This species of Hoverfly ( seen at the moment along the Severn), has the distinctive long snout of all the Rhingia species. Larvae are associated with cow dung. Adult males feed on nectar, while adult females feed on protein rich pollen
